The Watershed Protection and Partnership Council (WPPC) was created by the historic New York City Watershed Memorandum of Agreement to provide a regional forum to aid in the long term protection of New York City’s drinking water, and the economic vitality of the Upstate Watershed communities. Consisting of representatives from Watershed stakeholders, the Council brings the parties together - as partners - to share information and reports of progress as well as to identify issues of concern. It also provides a resource for dispute resolution. The Technical Advisory Committee, East of Hudson Advisory Committee and East of Hudson Sporting Advisory Committee provide sound technical support to the Executive Committee and the full Council.

About the NYC Watershed

The New York City Watershed is the largest unfiltered water supply in the United States, serving 9 million New Yorkers with about 1.3 billion gallons of clean drinking water each day.  The New York City Watershed spans nearly 2000 square miles, extends 125 miles north and west of New York City, and includes 19 reservoirs.  It is also home to nearly 1 million inhabitants.  This “living watershed” poses unique challenges to the scientists, engineers, managers, legislators, residents and stakeholders working and living within it.

Watershed Partnerships and Protection Council

Memorandum of Agreement set forth a comprehensive watershed management program enabling the city to continue supplying unfiltered water while providing for appropriate economic development in the upstate watershed communities. As part of the agreement, numerous Watershed Protection and Partnership Programs were established. The New York State Department of State administers certain partnership programs and serves the municipalities in the watershed.

The Water Quality Planning and Implementation Grants program, administered by the Department of State (DOS), is designed to assist watershed communities in preparing or updating comprehensive plans, establishing or revising community development tools and local laws, and creating strategic plans for hamlets, villages, and other potentially developable areas within the Watershed. Both East- and West-of-Hudson Watershed municipalities are eligible for the grants. No grants are being offered by DOS at this time. 

The New York City Department of Environmental Protection (DEP) partners with the New York State Environmental Facilities Corporation (EFC) in the East-of-Hudson area and Catskill Watershed Corporation (CWC) in the West-of-Hudson area to implement a series of programs designed to help protect water quality from septic system contamination. EFC provides financial and technical assistance primarily for water quality projects. The CWC administers water quality protection and economic development programs in the Catskill/Delaware (West of Hudson) Watershed.

DEP funds numerous programs that help to improve environmental infrastructure—especially stormwater management and wastewater treatment—while promoting and supporting environmentally sound economic development throughout the watershed region. For example, they have programs to extend sewers, build wastewater treatment plants, increase economic development, and manage stormwater.
